Now I get this P2141 code, from what I see this is not related to the tune, but there is so much misinformation about some of these codes on the internet I thought I would come to the place where I can get a concise description of what this code means.

SIMPLE FIX this time.
Took the GC to my local mechanic, he was also installing a rough Country 2" lift and his wife was checking the engine codes with their diagnostic tool, (big thing, dont know the make) but as she started and then shut the engine off her husband noticed that the breather pipe to the intake tube poped out from the valve cover, the pipe end was just sitting in the bushing and not secured, so he pushed it in and secured it with a zip tie, No more CEl or codes,
glad it was something simple this time.
